Abstract: Aspects described herein relate to a method comprising: receiving a request to write data to a persistent storage device, the request comprising data; determining an affinity of the data; writing the request to a cache line of a cache; associating the cache line with the affinity of the data; and reporting the data as having been written to the persistent storage device.

Abstract: A method comprising: receiving a request to read data stored in an array of drives; determining that the data is stored on one or more degraded drives in the array; reconstructing the data from one or more drives in the array other than the degraded drives; providing the reconstructed data in response to the request; and after providing the reconstructed data, writing the reconstructed data to one or more drives in the array other than the degraded drives.

Abstract: Aspects disclosed herein relate to a method comprising: obtaining a list of data paths to at least one persistent storage device through a plurality of NUMA nodes; associating with each data path, access performance information; receiving a request to access one of the at least one persistent storage device; calculating a preferred data path to the one of the at least one persistent storage device using the access performance information; and accessing the one of the at least one persistent storage device using the preferred data path.

Abstract: A method comprising: receiving, at a vector processor, a request to store data; performing, by the vector processor, one or more transforms on the data; and directly instructing, by the vector processor, one or more storage device to store the data; wherein performing one or more transforms on the data comprises: erasure encoding the data to generate n data fragments configured such that any k of the data fragments are usable to regenerate the data, where k is less than n; and wherein directly instructing one or more storage device to store the data comprises: directly instructing the one or more storage devices to store the plurality of data fragments.

Abstract: A method comprising: receiving a request to write data to a persistent storage device; writing the data to a cache line of a cache; pushing the cache line onto the end of a least recently used (LRU) queue of cache lines; and reporting the data as having been written to the persistent storage device.

Abstract: A method comprising: receiving a request to write data at a virtual location; writing the data to a physical location on a persistent storage device; and recording a mapping from the virtual location to the physical location; wherein the physical location corresponds to a next free block in a sequence of blocks on the persistent storage device.
